I was talking to a buddy who is pretty into 3D printing (and has printed various things for automotive applications) and he claimed that there was a readily available "automotive ABS" that could be used to print an intake and would easily stand up to the heat, vibration, fuel, etc. as it is the same material a lot of OEMs use for their intakes. He did mention it took a printer capable of higher temps but I found it intriguing...

I consider the rocker mod to be the one that brought all the pieces together, giving me a very nicely balanced car which also looks completely stock.
As for the RMP power limit, I can say unequivocally that the rockers made a huge difference. Where the stock car ran out of breath at about 4500RPM's, the modded car easily pulls all the way to 5500RPM's and there still some left but that's as far as I want to push a 30 year old engine even if it only has 60K miles on it. In fact, being an automatic I have to manually shift because the factory shift point is way too low for the modded engine.

As far as I am aware my engine is stock but it pulls super hard to 5500

K time for an update. I did lou_Dias mod (correction thanks fieroguru) on the middle intake as well as swapped my rockers to 1.6 rollers. That with my modded ppg style plenum and all the other work on my 3.4 ( ported heads sprint headers custom y pipe 260h cam bored TB tuned chip from sinister Etc etc) feels real good now. Fiero Gigi was right the modded middle intake let’s it breath all the way past 5500 rpm pulls through the whole power band now. A little torque lost on the bottom end for more top end speed feels great. Now I need to get it dyno’d. Mental number count from 0-60mph has me at low 5 seconds. Only need first and second gear to get there too

The idea and video on the modification to the middle intake was from lou_dias. I just liked the video to share the info.
I haven't done anything with a 60 degree V6 in about 15 years.

I just read through this whole 4 pages today, because the car I just got has the stock 2.8, and I have been trying to figure a way to push the envelope without making the car look modified. I REALLY want to just put an LS4/F40 in the car (I am in CA, the land of the NOT Free) I thought a 3.4 would be the ticket, make it look stock, but to make real power, cheaply it seems newer 3400 heads and intake are the way to go. Could someone make that look Fiero Stock? (I am adding 2 links, the story about power from a 3.4, and the ebay add with the same kind of heads/intake Rails/injectors that made power bolted to a camaro 3.4.
The camaro story is a little bit of reading, but the guy sounds pretty happy with the results, if you don't have the smog police that I do, this could be the way to go. For some reason, I don't think it would be completely easy to put 96 EFI parts, OBD2(rails/injectors) on the old 85 Fiero 2.8 wiring, I don't know enough yet about them.

HAVING TROUBLE GETTING LINKS TO WORK.........Ahh, OK
